So as I finished up my roof this weekend, I found that I have about 7-8 bundles of shingles left. I got to thinking about building a small (8'-12') shed for smoking. Can this be done safely; Carbon-Monoxide-wise? I'd like to put my smoker inside, and vent the intake and exaust lines through the wall. Of course while I'm at it, I'll add some counter tops, cabinets and a sink. While part of the reason is to shelter my pansy self from the cold, I also am trying to get all of my gear off the front porch. Anyone do anything like this?
